Shopping with London Power

London Power only supplies homes in London, so you'll need a London postcode for a quote. All the electricity it sells is matched with power from zero-carbon sources such as wind and sun.

Its plans are kept simple. There are no fees to leave, and when your plan ends it moves you to its cheapest similar plan automatically, so you don't drift onto a pricier rate.

London Power's published tariffs are in my energy comparison, so if you live in London you can see how London Power's plans compare with Octopus's own tariffs and the price cap.

To switch, enter your postcode on London Power's quote page. It tells your old supplier, and there's no engineer visit or break in supply.
